Mieo HA102: decoding a power meter's RF packets

The Mieo HA102 study reconstructs the power meter's 433.9 MHz FSK packet format from recorded signals. It maps current, cumulative consumption and battery fields, describes CRC16/SPI-FUJITSU checking, and supplies a Python decoder for live rtl_433 output or saved captures.
